FIELD: power industry.
SUBSTANCE: water supply device in section of combustion products containment and cooling chamber for solid propellant rocket engine charge liquidation comprises water distributing pipeline and spray nozzles. Arch-shaped spray nozzles are designed to generate pulverised water flux in the form of dispersed conical screen. Arch screen-generating spray nozzles are installed on water distributing pipeline inside of combustion products containment and cooling chamber section in amounts of 4 to 16 pieces per combustion products containment and cooling chamber section. Each arch screen-generating spray nozzle comprises 3 to 6 inlet fittings with diametre 20 to 40 mm, arch deflector with diametre 40 to 70 mm, which has 5 to 20 mm wide slotted opening with 45° expansion angle, and internal distributing cylinder with diametre 20 to 40 mm and openings for water outlet into mixing and reflecting chamber in amounts of 8 to 20 pieces.
EFFECT: effectivisation of combustion products cooling by pulverised large particle water flux.
